Verification procedure with active level
measurement
At normal operating conditions, compare the transmitter level, or interface reading, with an
independent measurement. Unfortunately, it often happens that two independent
measurements do not match up perfectly, but check the sanity and the acceptable deviation.
Verify the correctness of level reading
The independent measurement can be done using a number of different complementary
devices, ranging from sight-glasses and hand-dipping to redundant differential pressure and
displacer transmitters.
